Scope Notes

Glossary: (RF) active sensing active measure of the impedance formed between the finger and an electrode plate in the sensor, typically using RF band waves capacitive sensing static measure of the capacitance formed between the skin and an electrode plate in the sensor FTIR sensing frustrated total internal reflection sensing – the finger is imaged at the Brewster angle (air/glass); light rays are reflected only from the valley zones of the fingerprint, the ridges (partly) absorb the light. sweep sensor sweep sensors sensor acquiring partial fingerprint images and stitching them together to form a full fingerprint image
